fix(agents): finish sanitized config migration — GatewayClient also reads agents-sanitized.json

The previous commit f4bee44 updated AgentService.cs but missed
OpenClawGatewayClient.cs which also reads agent IDs and model config
from the raw openclaw.json. Both LoadAgentIdsFromConfig() and
GetAvailableModels() now default to /etc/nexus/agents-sanitized.json.

This completes the P4 migration: Nexus no longer needs read access to
openclaw.json for any code path.

-# Nexus Agent Guide
-
-## Scope
-
-These rules apply to the whole Nexus repository. Keep this file concise and
-update it when the build, architecture, or review workflow materially changes.
-
-## Product and architecture
-
-- Nexus is the Noveria operations platform. OpenClaw is integrated through the
-  backend runtime and bridge abstractions; frontend code must not depend on
-  OpenClaw internals.
-- `frontend/` is a Vue 3, TypeScript, Pinia, Vue Router, Vite, and Tailwind 4
-  application.
-- `backend/` is an ASP.NET Core 10 API using Entity Framework Core and
-  PostgreSQL.
-- `backend-tests/` contains the backend test project.
-- `frontend/src/api/` owns HTTP contracts, `frontend/src/stores/` owns client
-  state, and views/components should not duplicate transport logic.
-- Backend changes should preserve the controller -> service -> repository
-  boundaries and keep task mutations behind `ITaskBridgeService` where
-  applicable.
-
-## Required local checks
-
-Frontend:
-
-```powershell
-Set-Location frontend
-pnpm install --frozen-lockfile
-pnpm test
-pnpm build
-```
-
-Backend (requires .NET SDK 10):
-
-```powershell
-dotnet test backend-tests/Nexus.Api.Tests.csproj --configuration Release
-```
-
-Use the versions in CI as the compatibility baseline: .NET 10, Node.js 24, and
-pnpm 10.12.1. Do not silently downgrade target frameworks to match an older
-local SDK.
-
-## Security and review rules
-
-- Default API access to authenticated users or authenticated services. Public
-  endpoints must be explicitly marked and justified.
-- Never treat a caller-controlled identity header as proof of authentication
-  unless a trusted proxy removes and re-establishes it after authenticating the
-  caller.
-- Keep credentials and environment values out of tracked files. Use
-  `.env.template` only for documented placeholders.
-- Changes to authentication, agent commands, task mutation, deployment, or
-  database migrations require focused regression tests.
-- Frontend work must verify the registered route, loading/empty/error states,
-  keyboard semantics, and the 375, 768, 1024, 1440, and 1920 px breakpoints.
-- Do not add navigation entries without a registered route and a working
-  destination.
-
-## Documentation and evidence
-
-- Keep canonical technical documentation in this repository.
-- Put dated audit evidence in `docs/audits/YYYY-MM-DD/`.
-- Update `README.md` when routes, supported versions, deployment behavior, or
-  authentication contracts change.
-- At semantic checkpoints, update the compact Obsidian mirror under
-  `Projects/OpenClaw Mission Control/` after the repository documentation is
-  current. Do not copy large source files or detailed vulnerability mechanics
-  into the Vault.

-## Product target
-
-Nexus is the primary daily control plane for agents, tasks, runs, approvals,
-tools, schedules, knowledge and operational recovery. All agent and model
-execution travels through OpenClaw; OpenAI is the intended primary provider
-configured inside OpenClaw. Nexus does not call OpenAI directly. The browser
-and Nexus domain model stay independent of gateway and provider internals.
-
-The binding product and architecture direction is documented in
-[Agent-First Mission Control](docs/AGENT_FIRST_MISSION_CONTROL.md); the ordered
-feature plan is the [Mission Control Roadmap](docs/MISSION_CONTROL_ROADMAP.md).
-

 curl http://127.0.0.1:18880/health
 ```
 
 On an empty database the API creates exactly one owner from `BOOTSTRAP_OWNER_EMAIL`,
-derives the initial display name from that email, and hashes the explicitly configured
-`BOOTSTRAP_OWNER_PASSWORD`. Bootstrap credentials are never written to application logs.
+derives the initial display name from that email, and logs a generated temporary password once.
 After first seed the password lives only in PostgreSQL. Existing databases are
 never overwritten by the bootstrap process.
 
 The API is exposed via Traefik reverse-proxy with automatic Let's Encrypt TLS.
 Health checks, rate limiting, and security headers are active.
 
-## OpenClaw runtime data
+## Workspace mounts
 
-OpenClaw remains authoritative for its agents, bootstrap files, arbitrary
-workspace files, configuration and cron jobs. Nexus does not copy this state
-into a competing configuration:
+The API container mounts agent workspaces from the host for file browsing
+and the config editor. These are mounted under `/mnt/workspace-{agentId}`:
 
-- agent inventory comes from `agents.list`;
-- supported bootstrap files are read and written through
-  `agents.files.list/get/set`;
-- additional workspace files are browsed read-only through
-  `agents.workspace.list/get`; and
-- OpenClaw configuration is read and patched through
-  `config.schema.lookup`, `config.get` and `config.patch`.
-
-Agent inventory and configuration therefore do not depend on a
-`/mnt/workspace-{agentId}` naming convention. The owner-only Nexus
-Memory/Docs/Incidents read surfaces also resolve their live content through
-OpenClaw RPC. Their DTOs retain the source agent and safe workspace path so the
-UI can show provenance without mounting or inferring a host workspace.
+| Host path | Container mount |
+|---|---|
+| `/home/projekte_bao/openclaw/data/openclaw/workspace-iris` | `/mnt/workspace-iris` |

 ## Frontend architecture
 
-### Server-state and API boundary
+### Source layout
 
-- `backend/openapi/Nexus.Api.json` is the checked-in OpenAPI 3.1 contract.
-  `pnpm openapi:generate` produces
-  `frontend/src/api/generated/schema.d.ts`; CI rejects generated drift.
-- `frontend/src/api/` owns generated DTO use, typed requests, Query keys and
-  the common `ProblemDetails` adapter. Views must not reimplement transport
-  contracts.
-- TanStack Vue Query owns canonical reads for the Task Board, projects,
-  proposals, activity, notifications and the OpenClaw agent, overview, run,
-  cron, model, content and security domains. Shared Query keys deduplicate
-  consumers and preserve visible data during background refresh.
-- Pinia remains only for authentication, navigation/modals, local drafts,
-  setup/wizard workflow state and shared command facades. It is not a second
-  cache for canonical runtime collections.
-- A single authenticated fetch-based SSE hub parses domain events with a
-  bounded buffer, token refresh, abort, heartbeat and jittered reconnect.
-  Content-minimized deltas patch or invalidate only affected Query domains.
-- The old operations/task/notification/dashboard server-state stores, static
-  agent sources, duplicate live-sync modules and per-view SSE readers have
-  been removed after route and error-state parity checks.

-### App.vue route rendering
+### App.vue `standaloneViews` whitelist
 
-`/dashboard` uses `NexusLayout`; `/login` renders directly. Routes with
-`meta.standalone` render their registered view inside the shared legacy shell.
-Projects, Models and Activity are dedicated typed views. Iris chat is a
-global, on-demand modal on authenticated routes and has no separate `/chat`
-route.
+New views must be registered in the `standaloneViews` computed property in
+`App.vue` (line ~34). Without this entry, `RouterView` will not render the
+component — the route is valid but the template stays empty.
 
-### Live orchestration dashboard
+### New dashboard (Phase 2)
 
-The dashboard prioritizes the live agent topology:
+The dashboard was redesigned with a three-column layout:
 
-- **AlertBar** — compact active/planning/idle, usage and blocker status.
-- **FlowCanvas** — agent topology, selection, layout reset and model controls.
-- **TaskStrip** — compact focus tasks linked to the task workflow.
-- **IrisChat** — hidden by default and opened from the topbar as a modal.
-- **AgentDetailModal** — live summary, activity and model selection.
-
-### Global agent-first controls
-
-- `Ctrl/Cmd+K` opens a real command palette on every authenticated route.
-- The palette navigates to core surfaces and loaded projects, tasks, agents and
-  sessions. From a task, project or agent it can prefill a correlated durable
-  run.
-- “Ask Iris” sends only bounded route, surface, object-type and object-id
-  context. The backend labels this caller-provided context as untrusted
-  metadata before placing it ahead of the user's message.
-- Command and Iris dialogs are mutually exclusive and support keyboard
-  selection, dismissal and focus restoration.
-- Mission-control mutations publish one shared result tray with status,
-  revision, trace metadata and links to their primary and affected entities.

-deltas. A cursor older than the retained range returns `resync_required`;

-
-### Agent proposal and provisioning boundary
-
-Manual creation and Iris both create the same durable proposal:
-
-```text
-local form draft -> awaiting_approval -> provisioning
-                                      -> ready | partial | failed | in_doubt
-                 -> rejected
-```
-
-Iris has only `nexus_propose_agent` and `nexus_get_agent_proposal`; neither can
-approve or mutate OpenClaw. After explicit owner approval, the worker rechecks
-local management consent, the official external Client ID, endpoint/TLS trust,
-advertised capability, `operator.admin`, proposal revision and idempotency. It
-derives the workspace from server-side OpenClaw configuration, calls
-`agents.create` at most once, reads the inventory back and only then writes and
-verifies approved standard files. A timeout after possible dispatch becomes
-`in_doubt`; a later retry first reconciles `agents.list`. Post-create file
-failure becomes `partial` and never triggers an automatic agent deletion.
-
-Production provisioning remains disabled while the pinned OpenClaw version
-lacks an officially supported external Nexus or generic operator identity.
-
-Durable runs are stored in PostgreSQL before dispatch together with their
-transition history. They correlate OpenClaw run/session ids with optional
-Nexus task and project ids, actor, correlation id and trace context. Start,
-stop and retry are implemented. Same-run resume is deliberately disabled
-because the pinned Gateway contract does not currently advertise such an RPC.
-
-Nexus does not impersonate OpenClaw's reserved `gateway-client/backend`
-identity. Production attachment remains blocked until the pinned OpenClaw
-release officially supports the external `nexus` client id or another approved
-generic external-operator identity. Once that contract exists, remote or
-container-to-host operation uses Nexus' persisted Ed25519 identity and signed
-challenge response. The exact `PAIRING_REQUIRED` request id is surfaced to the
-owner; a resulting device token stays bound server-side to the normalized
-endpoint, TLS fingerprint and role. The Compose volume
-`nexus-openclaw-device` keeps identity state stable across API restarts and
-must be protected as credential material.
-See [OpenClaw Gateway connection](docs/OPENCLAW_GATEWAY_CONNECTION.md).
-
-Every typed OpenClaw mutation carries a Nexus invocation context with actor,
-correlation id, W3C `traceparent`, and idempotency key. The PostgreSQL claim
-store keeps only metadata and hashed idempotency keys. Because the current
-OpenClaw schemas for `tasks.cancel`, `sessions.abort`, `sessions.patch`,
-`cron.run`, and `approval.resolve` are closed and do not declare an
-`idempotencyKey`, Nexus deduplicates these calls locally instead of sending an
-undocumented field. Schema-confirmed methods such as `chat.send` can opt in to
-wire-level `idempotencyKey` propagation. Active claims and terminal outcomes
-are stored transactionally in PostgreSQL `OperationClaims`; any existing JSONL
-file is treated as an immutable legacy archive and is neither read nor
-appended by the registered store.

 Agent activity shown as "Thinking" is redacted before display. Lines containing
 token, password, bearer, authorization, API key or secret markers are replaced
 with a redaction marker. Persisted audit-worthy events should be written as
 short Activity entries, not raw session transcripts.
 
-Dashboard and agent telemetry no longer invent progress, elapsed time, next
-steps, cost or synthetic “Thinking” items. Progress is shown only when a Nexus
-task reports it, token totals only when a Gateway session reports them, and
-unreported values are rendered as unknown. Cost remains unknown until the
-runtime supplies authoritative cost data.
+Nexus activity updates stream live through the Dashboard SSE channel and are
+filtered by explicit `agentIds`. Gateway session history is read-only fallback
+data: it is fetched on demand, redacted before display and not persisted as a
+long-term raw transcript. Agent "Now" and "Today" summaries are deterministic
+derivations from redacted Nexus activity plus redacted Gateway history; Nexus
+does not call an LLM to summarize this feed.

-# Backend tests

-The normal test command remains Docker-free:
-
-```powershell
-dotnet test Nexus.Api.Tests.csproj --configuration Release
-```
-
-Docker-backed tests are discovered but skipped unless explicitly enabled.
-They use `postgres:17-alpine`; the optional network-fault contract additionally
-uses Testcontainers Toxiproxy and a pinned lightweight OpenClaw HTTP stub.
-
-```powershell
-$env:NEXUS_RUN_DOCKER_INTEGRATION_TESTS = "true"
-dotnet test Nexus.Api.Tests.csproj --configuration Release `
-  --filter "Category=DockerIntegration"
-```
-
-Enable the slower Toxiproxy case as well:
-
-```powershell
-$env:NEXUS_RUN_DOCKER_INTEGRATION_TESTS = "true"
-$env:NEXUS_RUN_TOXIPROXY_INTEGRATION_TESTS = "true"
-dotnet test Nexus.Api.Tests.csproj --configuration Release `
-  --filter "Category=DockerIntegration"
-```
-
-Once opted in, an unavailable Docker daemon is a test failure rather than a
-silent skip. In Gitea Actions, set the repository variable
-`NEXUS_RUN_DOCKER_INTEGRATION_TESTS=true`; optionally set
-`NEXUS_RUN_TOXIPROXY_INTEGRATION_TESTS=true` for the timeout contract. The
-selected runner must expose a working Docker endpoint to Testcontainers.
